I seem to have all the correct packages outlined in the docs, I just don't know why it's not working now.

Can you share more information? Which OS are you using? ARM / x86? Exact steps you use to build?

I'm on nixos but I opened a distrobox ubuntu container to try to compile everything and I followed the build instructions on the readme

selsta commented 1 month ago

Which Ubuntu version is used? Is this indistinguishable from a regular Ubuntu install?

Might be related, check this out too:

Redhawk18 commented 1 month ago

I'll try on nixos again and if I can get it working I'll pr my flake for so no other nixos user will have problems compiling.

I tried building on nixos again and got this new error this time

A weird thing is I added gnu's readline library because cmake complained and it still doesn't find it.

0xFFFC0000 commented 1 day ago

This says it needs zlib library when building master [1].

I have PR to fix this. But for now you can add zlib in your Nix package description. ( I did roughly the same with GUIX ).

Another issue you mentioned is gnu readline library, is because the Cmake file for finding it does not interact correctly with sandboxed build ( like nix / guix ). This fixes it [2]. Or you can fix it the way GUIX fixed it [3].
